With the current "Type=forking", systemd tries to guess the PID it
should wait on at reboot (because we have no "PIDFile="). Depending on
how wrong the guess is, we can end up hanging forever at reboot.
Asking it not to do that eliminates the problem.
If we not marking manager dirty when link is dirty then

When building without resolved and/or myhostname, test-nss.c failed to build

Ensure that all MODULEx are always defined, and empty if the module is not
available (so that it will be a no-op in the string concatenation).
We enable lingering for anyone who wants this. It is still disabled by
default to avoid keeping long-running processes accidentally.
Admins might want to customize this policy on multi-user sites.
Instead of KillOnlyUsers being a filter for KillUserProcesses, it can now be
used to specify users to kill, independently of the KillUserProcesses
setting. Having the settings orthogonal seems to make more sense. It also
makes KillOnlyUsers symmetrical to KillExcludeUsers.
This ensures that users sessions are properly cleaned up after.
The admin can still enable or disable linger for specific users to allow
them to run processes after they log out. Doing that through the user
session is much cleaner and provides better control.
dbus daemon can now be run in the user session (with --enable-user-session,
added in 1.10.2), and most distributions opted to pick this configuration.
In the normal case it makes a lot of sense to kill remaining processes.
The exception is stuff like screen and tmux. But it's easy enough to
work around, a simple example was added to the man page in previous
commit. In the long run those services should integrate with the systemd
users session on their own.
https://bugs.freedesktop.org/show_bug.cgi?id=94508https://github.com/systemd/systemd/issues/2900
The description in the man page was wrong, KillUserProcesses does
not kill all processes of the user. Describe what the setting
does, and also add links between the relavant sections of the
manual.
Also, add an extensive example which shows how to launch screen
in the background.
SELinux outputs semi-random messages like "Unknown permission start for class
system", and the user has to dig into message metadata to find out where
they are comming from. Add a prefix to give a hint.
IPv6 protocol requires a minimum MTU of 1280 bytes on the interface.
This fixes#3046.
Introduce helper link_ipv6_enabled() to figure out whether IPV6 is enabled.
Introduce network_has_static_ipv6_addresses() to find out if any static
ipv6 address configured.
If IPv6 is not configured on any interface that is SLAAC, DHCPv6 and static
IPv6 addresses not configured, then IPv6 will be automatically disabled for that
interface, that is we write "1" to /proc/sys/net/ipv6/conf//disable_ipv6.
I wanted to add a config line that would empty a directory
without creating it if doesn't exist. Existing actions don't allow
this.
v2: properly add 'e' to needs_glob() and takes_ownership()
- do not suggest that vendor configuration files should be in
/etc, use /usr/lib/tmpfiles.d instead
- split the first example, because the text talked about "needing
two directories", but then a smack attribute was also set, and
on a different path, which looked like a typo. Replace that
with the example from original patch [1] which added 't'.
- fix the example for /var/tmp/abrt. The 'x' line was redundant,
because /var/tmp/abrt/* is already filtered because "d /var/tmp/abrt"
overrides "d /var/tmp".

This changes the behaviour of pid1 in the following ways:
- obviously $TERM is now checked,
- $SYSTEMD_COLORS is now honoured too, before only SYSTEMD_LOG_COLORS was checked,
- isatty() is run on stdout not stderr.
As requested in #3025.
After all it's something that we query over and over.
For example, systemctl calls colors_enabled() four times for each failing
service. The compiler is unable to optimize those calls away because they
(potentially) accesses external and global state through on_tty() and
getenv().
No need to dump all the redundant device units on the user, just because he
specified that he wants to see units of a specific state.
This was broken by commit ebc962656c.
Don't leave temporary files if the coredump service is aborted during
the operation
Yeah, these are temporary files that systemd-coredump needs while
processing the coredumps. Of course, if the coredump service is aborted
during the operation we better shouldn't leave those files around. This
is hence a bug to fix in our coredumping code.
See https://github.com/systemd/systemd/issues/2804#issuecomment-210578147
Another option is to simply use O_TMPFILE, and when it is not available
fall back to the current behaviour. After all, the files are cleaned up
eventually, through normal tmpfiles aging, and the offending file
systems are pretty exotic these days, or not in the upstream kernel.
See https://github.com/systemd/systemd/issues/2804#issuecomment-211496707
-1 could be confused with -EPERM. But we still need a negative enum
value to force gcc to use int for the enum type, even though it is
unused. Otherwise we get warnings.
Fixes#2191:

(I tried a few different approaches to pass the error information back to the
caller. Adding a new parameter to hold the error results in a gigantic patch
and a lot of hassle to pass the args arounds. Adding this information to the
changes array is straightforward and can be more easily extended in the
future.)
In case local installation is performed, the full set of errors can be reported
and we do that. When running over dbus, only the first error is reported.
This new feature bypasses checking if a swap partition is mounted
or if there is enough swap space available for hibernation to
succeed.
This can be useful when a system with a Solid State Disk (SSD)
has no normal swap partition or file configured, and a custom
systemd unit is used to mount a swap file just before hibernating
and unmount it just after resuming.

* man: change time unit specifier for minutes to "m", not "min".
To alert the reader to the fact that the ambiguous prefix "m" will be
interpreted as minutes, not months.
* man: change 'journal files' to 'archived journal files'.
So that the user may be reminded why they see log entries in the journal
from a time previous to the one they specified when using --vacuum-time.
Currently, 99-systemd.rules.in contains a line for network block
devices, which mark them as inactive until the first change event, and
as active from then on forward. This is not correct. A network block
device can be connected or disconnected; this state is signalled by the
presence or absense of a "pid" file, which contains the PID of the
nbd client userspace process that started the connection.
Update the rules file so that it checks for the presence of that file to
decide what to set SYSTEMD_READY to.
Note that current kernels do issue a change event upon connecting the
device, but not yet upon disconnecting. While it's possible to wait
until that's been fixed, the behaviour of the rule with TEST!="pid" in
the absence of a proper uevent is exactly the same as the behaviour of
the old rule; so it should be safe to apply now.

If you reference another unit with an escaped name, the escaped characters
should remain in the extracted word. This used to work correctly prior to
commit 34f253f0.
The problem can be seen when units with escaped names are referenced.
